Abstract: Abstract FOLD OVER FILTER CLIP AND OSTOMY    BAG FOR USE WITH SAME       A fold-over filter clip for use on an ostomy bag having first and second members joined together or hinged together and made from a material which can be readily bent by human finger pressure. One of these members has a bag-puncturing spike extending outwardly from a substantially flat surface thereon and an adhesive covered by a strippable protective layer on said flat surface.  The other of the members defines a space in which a pad of gas adsorbing material is located and also has a layer of adhesive covered by a strippable protective layer across its top except in the region which aligns with the spike when the filter is bent into its closed position.      An ostomy bag particularly adapted for use with such filter is also disclosed.  The bag has an upper region to which the filter is attached defined by a discontinuous join connecting the bag walls. The join permits the flow of gas into the upper bag region through one or more gaps therein but impedes the flow of fecal material which could clog the filter.

Abstract: Abstract of the Disclosure 2-Keto-L-gulonic acid is prepared directly from D-glucose by microbial conversion utilizing mixed culturing on a medium containing D-glucose, employing two kind of microorganisms; the first, a 2,5-diketo-D-gluconic acid producing microorganism which belongs to genus Erwinia and the second, a 2-keto-L-gulonic acid producing microorganism which belongs to genus Brevibacterium or Corynebacterium.          The incubation of the microorganisms in a medium containing D-glucose is used in the disclosed process.  By-production of 2-keto-D-gluconic acid, the undesired isomer of the intended product is effectively prevented by employing the mixed culturing because of the co-existence of the both microorganisms in the medium during at least part of the entire cultivation.  Namely, 2-keto-D-gluconic acid produced by the second microorganism is utilized by the first microorganism to produce 2,5-diketo-D-gluconic acid which is subsequently converted into 2-keto-L-gulonic acid by the second microorganism.

Abstract: ABSTRACT         An osmotic device is disclosed for delivering two beneficial drugs to an environment of use.  The device comprises a wall surrounding a lumen divided into a first compartment containing a drug that is separated by a hydrogel partition from a second compartment containing a different drug.  An orifice through the wall communicates with the first compartment for delivering drug formulation from the first compartment, and another orifice through the wall communicates with the second compartment for delivering drug formulation from the second compartment.  In operation, drug formulation is dispensed separately from each compartment by fluid being imbibed through the wall into each compartment at a rate controlled by the permeability of the wall and the osmotic pressure gradient across the wall against the drug formulation in each compartment thereby producing in each compartment a solution containing drug, and by the expansion and swelling of the hydrogel, whereby drug formulation is dispensed through their orifices at a controlled and continuous rate over a prolonged period of time.

Abstract: ABSTRACT OF THE DISCLOSURE        The liner includes a generally C-shaped, flexible band of bearing material disposed to be placed around the drop center of a tire rim,  Two, complimentary, generally semi-circular members made from a polyester elastomer are then mounted as a ring coaxially around the outside of the band with the inner peripheral surfaces thereof slidably seated in a circumferential groove that is formed in the outer periphery of the band.  The confronting ends of the members are releasably secured together by a pair of rigid links, each of which is releasably and pivotally mounted at one end in a recess in one end of a member, and has its opposite end connected to a rotatable eccentric that is mounted in the confronting end of the other member. When the associated eccentric is rotated, it causes the attached link to be reciprocated further into, or out of, the end of the associated member, thereby causing the link selectively to shift confronting ends of the members toward or away from each other. In one embodiment the C-shaped band is a one-piece element, while in another a layer of metal (for example galvanized steel) is mounted in the outer groove of the band to be interposed between the band and the ring members.

Abstract: Abstract A process is described for concentrating a mixed martite/hematite ore using wet high intensity magnetic separators, such as Jones Separators.  A slurry of the mixed ore is first passed through a primary grooved-plate high intensity wet magnetic separator having plate gaps of 3 mm to 15 mm, groove widths 1 to 3 times the gap distance and a magnetic intensity of 2000 to 10000 gauss, thereby separating the slurry into a first magnetic stream, a first middling stream and a first non-magnetic stream.         This first magnetic stream is collected as product and the first middling stream and first non-magnetic stream are combined to become a feed slurry through a secondary grooved plate high intensity wet magnetic separator having plate gaps of 1 mm to 3 mm, groove widths of less than about 4 mm and a magnetic intensity of about 5000 to 15000 gauss, thereby again separating the slurry into a second magnetic stream, a second middling stream and a second non-magnetic stream. The second magnetic stream is also collected as product.

Abstract: NETWORK PROTOCOL FOR INTEGRATING SYNCHRONOUS  AND ASYNCHRONOUS TRAFFIC ON A COMMON SERIAL                  DATA BUS     Abstract Contention among a plurality of synchronous and asynchronous devices connected to a shared communication medium for access to time slots in a sequence of frames is resolved by assigning a unique priority word including a priority code prefix to each device and granting access to a given slot by comparing the value of the priority words assigned to completing devices. The priority code prefix is assigned as a joint function of whether synchronous or asynchronous communication is desired and whether synchronous communication is being initiated or continued. In each assignment protocol, synchronous communication is enabled by assuring any device that initially gains access to a particular time slot continued access to the same slot in succeeding frames.  If desired, devices with synchronous access may relinquish unused time slots to asynchronous traffic, while reserving the ability to resume synchronous communication.
